RE: CAC-1070 and 1170 HDMI 2.0 adapter feedback topic.

I am having issues with my two CAC-1170 adapters on the Intel HD Graphics 4600 platform – I still cannot achieve 60Hz at 3840 x 2160 resolution.

I have enabled UHD Color on my Samsung UE48JU7500 2015 Series TV and it has made no difference – I’ve even tried it on other HDMI ports on the TV as well as setting the device to “PC” but this didn’t work either.

I’ve got two PC’s, a custom built machine with the ASRock Q87M vPro, I have double checked and confirmed this has DP 1.2, I also have a Dell OptiPlex 7020 PC, this has DP 1.2 as well.  Both PC’s have the Intel i5-4590 CPU (http://ark.intel.com/products/80815/Intel-Core-i5-4590-Processor-6M-Cache-up-to-3_70-GHz)

As you can see on the ARK, the Intel HD 4600 Graphics definitely supports 3840×2160@60Hz over the DisplayPort so I am now baffled what to do as I have no other graphics card to try these adapters on.

Please can you advise or tell me how I flag this up with Club3D support directly? The Club3D site for the CAC-1070 definitely says it is compatible with Intel Graphics solutions:
Supports AMD, Nvidia® and Intel® HD/ Iris™ graphics solutions

Can I possibly try the new firmware?

Thanks
